Definitions

  • the present invention in particular is directed to a method of treating soiled inner walls of an oven cavity, in particular an oven cavity of a baking oven of household type, for example.
  • a method of treating soiled inner walls of an oven cavity in or during a cleansing process is provided.
  • the oven in particular may be a baking oven, in particular a domestic baking oven.
  • the oven cavity may also be referred to as an oven muffle.
  • the method comprises a step of mechanically nebulising with an automatic, self-contained cleansing unit a cleansing liquid, in particular into the oven cavity, for generating a mist of the cleansing liquid within or into the oven cavity.
  • the term "ge ⁇ nerating a mist of the cleansing liquid within or into the oven cavity” in particular shall mean that the mist finally will be in, i.e. within, the oven cavity, in particular will penetrate or spread within the inner volume of the oven cavity.
  • mist or fog may but does not necessarily has to be generated directly within the oven cavi ⁇ ty.
  • Mechanically generating the mist of cleansing liquid shall exclude generating mist by heating, i.e. applying heat energy to, the cleansing liquid.
  • the mist or fog of the cleansing liquid can be generated in a com ⁇ paratively easy way.
  • a mist or fog of the clean- sing liquid can be generated until the inner walls of the bak ⁇ ing chamber are evenly loaded with cleansing liquid sufficient to soak deposited dirt and soiling matter.
  • the terms "automatic” and "self-contained” in particular shall mean that the process of generating the mist or fog of cleansing liquid as such does not require user interaction or user actions. After activating the cleansing unit, the mist or fog may be generated automatically without any further user interaction.
  • Soil on inner walls of an oven cavity in general is generated by foodstuff and related substances, such as oil and the like, deposited on the cavity walls during use, i.e. baking, and, in particular burning-in during baking or cooking processes. Respective soiled inner cavity walls in many cases are difficult to clean.
  • the mist or fog of cleansing liquid mechanically generated spreads within the oven muffle or cavity, gets in contact with the soiled inner walls, in par ⁇ ticular is deposited on the soiled inner walls, and soaks soil- ing matter or dirt adhering to the cavity walls.
  • the inner walls of the oven cavity can be cleaned much easier as compared to soiled walls where soiling matter or dirt is not soaked with a cleansing liquid.
  • the oven cavity is closed and kept closed. In the closed state, the inner walls can be far better charged or loaded with the mist of cleansing liquid, and therefore deposited dirt and soiling matter can be soaked with cleansing liquid more efficiently.
  • a further advantage of the proposed method is that the mist of cleansing liquid can be generated comparatively energy- efficient, as compared for example with solutions in which a mist of cleansing liquid is generated by thermal vaporization.
  • nebulising the cleansing liquid comprises applying at least one of a pres ⁇ surized gas and ultrasonic wave energy to the cleansing liquid.
  • the pressurized gas may for example be generated by a, in par ⁇ ticular small, compressor.
  • Other devices for supplying gas such as gas cylinders and the like, may be used.
  • ultrasonic atomizers in particular piezoelectric wave generators, may be used.
  • the proposed mechanical variants for generating the mist or fog of cleansing liquid are comparatively easy and can be operated energy efficiently. Further, generating the mist or fog without the application of thermal energy, in particular without heating the cleansing liquid and inner space of the oven cavity, reduces the danger of burns and lesions on or at hot surfaces, in particular hot inner walls, of the oven cavity. In other words, in executing the proposed method, the soiling matter and dirt may be soaked with cleansing liquid without further heating up the inner walls. The soiled matter and dirt can be mechanically removed by a user on comparatively cool in ⁇ ner walls.
  • nebu ⁇ lised cleansing liquid is distributed within the oven cavity by the action of a fan.
  • a fan can enhance uniform distribution of the mist or fog of cleansing liquid within the oven cavity.
  • dirt deposited in the inner cavity walls can be soaked uniformly in almost all sections of the in- ner wall of the oven cavity. Therefore, a subsequent mechanical cleaning, in particular a step of mechanically wiping off the inner walls of the cavity by a user, can be facilitated even for sections of the oven cavity that are difficult to access.
  • the fan used for distributing the nebulised cleansing liquid may be the fan of the oven intended and generally provided for recirculating air during cooking or baking processes.
  • a respective nebulising unit at least an exit opening for the atomized or nebulised cleansing liquid, is mounted or placed close to the recirculating fan of the oven.
  • the nebulising unit may comprise its own fan, in particular a fan separate from the recirculating fan, intended for recirculating air during baking or cooking.
  • the proposed method comprises a further step of mechanically removing soil, in particular dirt or soil ⁇ ing matter, soaked with the cleansing liquid.
  • the oven cavity may, at least in some sections, comprise mechanical ac- tuators adapted for mechanically removing the soaked dirt or soil.
  • the step of removing the soaked soil may also involve user interaction, in particular as indicated further above .
  • an oven in particular a baking oven, preferably of household type, is provided.
  • the proposed oven comprises an oven cavity and an automatic, self-contained cleansing unit.
  • the cleansing unit is adapted to treat soiled inner walls of the oven cavity with a cleansing liquid.
  • the treatment of the inner walls by the cleansing unit is conducted according to a method as proposed further above, in particular including any embodiments of the proposed method.
  • the cleansing unit can generate the mist or fog of cleansing liquid without any further user interac ⁇ tion.
  • the cleansing unit in particular can be implemented as a small apparatus adapted to generate a mist of cleansing liquid after activation, and to stop the generation of the mist of cleansing liquid after switching-off or deactivation.
  • the proposed oven has the advantage that cleaning of the inner walls can be conducted in a comparatively energy efficient and user friendly way.
  • the cleansing unit comprises a compartment for accommodating the cleansing liquid.
  • the compartment may be a component, in particular a fixed component of the oven, in particular of an inner wall of the oven, such for example a bottom or side wall of the oven cavity.
  • the compartment may be a moveable compartment, adapted to be freely placed into and within the oven cavity.
  • Such a separate compartment may be provided as an accessory part of the oven.
  • the cleansing liquid in the sense of the invention may be water, a detergent or a mixture thereof, i.e. a mixture of water and a detergent.
  • the compartment may be a comparatively small container, with a volumetric capacity far below that of the oven cavity.
  • the vo ⁇ lumetric capacity of the compartment may in particular be se ⁇ lected such that a volume of cleansing liquid for conducting a single cleansing process can be accommodated in the compart- ment .
  • This means that all cleansing liquid contained in the compartment is nebulised in a single cleansing action.
  • the volumetric capacity of the compartment may in the alterna- tive be such that the cleansing liquid within the compartment is enough or sufficient for several cleansing operations.
  • Dimensioning the compartment such that only a single cleansing action can be performed, i.e. such that essentially no further cleansing liquid is contained in the compartment after finish ⁇ ing a cleansing action has the advantage, that in a subsequent operation of the oven, in which the oven cavity is heated up, essentially no cleansing liquid is present and will be vapo- rized by the heat generated by heating elements of the oven.
  • the cleansing unit further comprises a nebulising unit implemented to mechanically nebulise the clean ⁇ sing liquid by at least one of applying pressurized gas and ul ⁇ trasonic waves to the cleansing liquid.
  • nebulising unit has the advantage that a mist or fog of cleansing liquid can be generated in a comparatively energy ef ⁇ ficient way, in particular as compared to generating a mist or fog of cleansing liquid by thermally vaporizing the cleansing liquid .
